All-terrain load transport system

ABSTRACT

An all-terrain load transport system including a cylindrical first base member and at least three pairs of arms is provided. A handle is removably attached to an attachment member disposed on the cylindrical first base member. The cylindrical first base member defines a space for receiving at least one piece of accessory equipment. Each pair of the three pairs of arms defines a wheel support assembly at an end of each pair distal from an outer periphery of the cylindrical first base member. The three pairs of arms are detachably attached to the outer periphery of the cylindrical first base member. The wheel support assembly includes a cylindrical second base member defining a space for receiving a spherical wheel. The spherical wheel moves omnidirectionally within the defined space. Roller bearings positioned along an inner periphery of the cylindrical second base member facilitate the omnidirectional movement of the spherical wheel.

BACKGROUND

Most load transport systems, for example, carts, platform dollies, trollies, etc., cannot efficiently maneuver on uneven or rough terrains. Although load transport systems may be able to move heavy loads, their movement is often obstructed by small surface irregularities. For example, when a load transport system is transporting a heavy load, an object as thin as a coin may obstruct forward movement of the load transport system. Forward movement may also be obstructed by an abrupt upward change in the plane of travel of the load transport system. For example, when an irregular surface or an inclined surface is encountered, the entire load carried by the load transport system is shifted to one or more rollers still in contact with the surface over which the load is being moved. The rollers still in contact with the surface must be able to support the weight of the entire load carried by the load transport system, necessitating the use of large rollers. Moreover, due to the small diameter of the rollers typically employed in load transport systems, small irregularities in the surface over which the load transport system traverses will have a magnified effect upon the amount of energy required to move the loaded load transport system over the irregular or inclined surface. To overcome these drawbacks, a load transport system provided with suitably large, rigid roller wheels may be used. However, such roller wheels may dig into the contact surface if the surface is uneven or irregular. Accordingly, there is a need for a cart or load transport system that traverses even and uneven terrains with no damage or minimal damage to the contact surface or the roller wheel of the cart or load transport system.

Conventionally, most load transport systems are not expandable or adjustable to handle different sized loads and are not multi-functional, making it difficult to load accessories or equipment of varied sizes and shapes, thereby increasing the probability of the load falling off the load transport system. Therefore, there is a need for a cart or load transport system that allows mounting of equipment or accessories or loads of varying sizes and shapes. A drawback of conventional carts includes exertion of frictional force or resistive force on the roller wheels by a support assembly of the roller wheels. Typical roller wheel assemblies allow movement in a single direction or in only two directions within their roller wheel housings, which leads to increased friction on the external surface of the roller wheels, thereby causing wear and tear and reducing the life of the roller wheels. Therefore, there is a need for a load transport system comprising a roller wheel assembly having improved freedom of movement with reduced friction.

Furthermore, other challenges in conventional load transport systems result from the use of steel wheels or rollers in their construction. The steel wheels may damage the surface over which they travel, especially over tiled surfaces typically encountered in office buildings and the like. Another drawback with steel wheels is their ability to transmit the unevenness of the surface over which they travel to the equipment in the load transport system in the form of mechanical vibrations which may not be tolerated by sensitive equipment such as electronic equipment, computers, etc. Therefore, there is a need for a load transport system comprising a roller wheel assembly that exerts minimal force on a floor or ground surface and reduces the impact of uneven ground surfaces on the mounted equipment.

Hence, there is a long-felt need for a load transport system that traverses even and uneven terrains, with no damage or minimal damage to the contact surface, or to the roller wheel of the load transport system. Moreover, there is a need for a load transport system that allows mounting of equipment or accessories or loads of varying sizes and shapes on the load transport system. Furthermore, there is a need for a load transport system comprising a roller wheel assembly having improved freedom of movement with reduced friction. Furthermore, there is a need for a load transport system comprising a roller wheel assembly that exerts minimal force on a floor or ground surface and reduces the impact of uneven ground surfaces on equipment mounted on the load transport system.

DETAILED DESCRIPTION

FIG. 1A exemplarily illustrates an exploded, top perspective view of an all-terrain load transport system 100. The all-terrain load transport system 100 comprises a substantially cylindrical first base member 101 and at least three pairs of arms 102 a, 102 b, and 102 c. As used herein, “substantially cylindrical” refers to a geometrical configuration such as right circular cylindrical, oblique cylindrical, elliptical cylindrical, hollow cylindrical, and the like. Moreover, “substantially cylindrical” configurations may also be construed to include cylindrical members having a circular cross-section, an oval cross-section, a conical cross-section, and similar variants that are known in the art. In an embodiment, the substantially cylindrical first base member 101 is, for example, a hoop-type structure or a ring-type structure. Furthermore, the height or thickness of the substantially cylindrical first base member 101 is different for different implementations of the all-terrain load transport system 100. For example, an all-terrain load transport system 100 configured to receive heavy equipment is of a greater height and thickness than a similar all-terrain load transport system 100 configured to receive light equipment. As used herein, “height or thickness” of the substantially cylindrical first base member 101 refers to the height or thickness of a lateral surface of the substantially cylindrical first base member 101. The substantially cylindrical first base member 101 defines a space 114 for receiving at least one piece of accessory equipment, for example, any one of a welding accessory 600, a vacuum cleaning accessory 700, a pressure washing accessory 800, an airless paint spraying accessory 900, a beverage cooling accessory 1000, an air compressor accessory 1100, a wheelbarrow accessory 1200, a trash can accessory 1300, etc., as exemplarily illustrated in FIGS. 6-13 .

Each pair of the three pairs of arms 102 a, 102 b, and 102 c of the all-terrain load transport system 100 defines a wheel support assembly 103. The three pairs of arms 102 a, 102 b, and 102 c are detachably attached to an outer periphery 101 a of the substantially cylindrical first base member 101. As used herein, “detachably attached” refers to a method of attachment or connection that allows the arms 102 a, 102 b, and 102 c to be removable. For example, the three pairs of arms 102 a, 102 b, and 102 c are detachably attached to the outer periphery 101 a of the substantially cylindrical first base member 101 using male attachment members 102 d configured to be inserted into sockets 101 b defined within the substantially cylindrical first base member 101. In an embodiment, the male attachment member 102 d is one of a projection, a pin, a threaded bolt, an alignment post, a mounting boss, a sheet metal tab connector, a ball and socket joint, etc. Correspondingly, the socket 101 b is a female connecting member such as one of a recess, a plain socket, a threaded nut, an alignment hole, a mounting recess, a sheet metal slot connector, etc. In an embodiment, the male attachment members 102 d are wedge-shaped and the sockets 101 b are shaped correspondingly to receive the wedge-shaped male attachment members 102 d.

The wheel support assembly 103 is defined at an end 102 a′ of each pair of the three pairs of the arms 102 a, 102 b, and 102 c distal from the outer periphery 101 a of the substantially cylindrical first base member 101. Each wheel support assembly 103 comprises a substantially cylindrical second base member 104, a spherical wheel 105, and roller bearings 106. The substantially cylindrical second base member 104 extends from the end 102 a′ of each pair of the three pairs of arms 102 a, 102 b, and 102 c. Each substantially cylindrical second base member 104 defines a space 104 a for receiving a spherical wheel 105. The spherical wheel 105 is configured to move omnidirectionally within the space 104 a. The omnidirectional movement of the spherical wheel 105 is facilitated by multiple roller bearings 106 positioned along an inner periphery 104 b of the substantially cylindrical second base member 104. In an embodiment, the wheel support assembly 103 further comprises a top dust seal 107 and a bottom dust seal 108. In an embodiment, the top dust seal 107 is seated proximal to a top surface 104 c of the substantially cylindrical second base member 104, and the bottom dust seal 108 is seated proximal to a bottom surface 104 d of the substantially cylindrical second base member 104. The top dust seal 107 and the bottom dust seal 108 are configured to prevent ingress of particulate matter, for example, dust, into the space 104 a defined by the substantially cylindrical second base member 104. Each of the three pairs of arms 102 a, 102 b, and 102 c comprises a pair of angled members 102 e and 102 f as exemplarily illustrated in FIGS. 1A-1C and FIGS. 1E-1G, that projects laterally from the side of the substantially cylindrical second base member 104. The pair of angled members 102 e and 102 f is angled with respect to a plane of the substantially cylindrical second base member 104.

In an embodiment, the all-terrain load transport system 100 further comprises a handle 109 removably attached to an attachment member 110 disposed on the outer periphery 101 a of the substantially cylindrical first base member 101. The handle 109 is removably attached to the attachment member 110 using a fastener 110 a. The handle 109 facilitates maneuvering of the all-terrain load transport system 100. Several supplementary attachment members 110 are similarly disposed at various locations along the outer periphery 101 a of the substantially cylindrical first base member 101 for removably attaching one or more pieces of accessory equipment to the all-terrain load transport system 100.

FIG. 1B exemplarily illustrates an exploded, front view of the all-terrain load transport system 100. As exemplarily illustrated in FIG. 1B, the substantially cylindrical first base member 101 comprises an interior support ring 112 attached to the bottom end 111 of the substantially cylindrical first base member 101. The interior support ring 112 is, for example, made of metal to increase the strength of the substantially cylindrical first base member 101. The interior support ring 112 is coaxial to the substantially cylindrical first base member 101. As exemplarily illustrated in FIGS. 1A-1B, each of the arms 102 a, 102 b, and 102 c of the all-terrain load transport system 100 comprises, for example, about ten roller bearings 106. About five roller bearings 106 are disposed proximal to the top dust seal 107, and about five roller bearings 106 are disposed proximal to the bottom dust seal 108. In an embodiment, the roller bearings 106 are of a roller-type construction. In another embodiment, the roller bearings 106 are of a ball-type construction.

FIG. 1C exemplarily illustrates a top view of a wheel support assembly 103 being affixed to the substantially cylindrical first base member 101 of the all-terrain load transport system 100 shown in FIGS. 1A-1B and FIGS. 2-3 . One pair of arms 102 a is shown as being detachably attached to the substantially cylindrical first base member 101 in FIG. 1C. The arms 102 a comprise angled members 102 e and 102 f and male attachment members 102 d, which allow the arms 102 a to be removable. For example, the male attachment members 102 d are configured to be inserted into corresponding sockets 101 b defined within the substantially cylindrical first base member 101. Correspondingly, each socket 101 b is a female connecting member, for example, one of a recess, a plain socket, a threaded nut, an alignment hole, a mounting recess, a sheet metal slot connector, etc. In an embodiment, the male attachment members 102 d are wedge-shaped and the corresponding sockets 101 b are shaped correspondingly to receive the wedge-shaped male attachment members 102 d as exemplarily illustrated in FIG. 1C. Moreover, the pair of arms 102 a defines the wheel support assembly 103 at an end 102 a′ of the pair of the arms 102 a distal from the substantially cylindrical first base member 101.

FIG. 1D exemplarily illustrates a right-side view of the wheel support assembly 103 being affixed to the substantially cylindrical first base member 101 of the all-terrain load transport system 100 shown in FIGS. 1A-1B and FIGS. 2-3 . The wheel support assembly 103 comprising the substantially cylindrical second base member 104, the spherical wheel 105, the roller bearings 106 shown in FIGS. 1A-1B, the top dust seal 107, and the bottom dust seal 108, extends from the end 102 a′ of the arms 102 a distal from the substantially cylindrical first base member 101. The substantially cylindrical second base member 104 extends from the end 102 a′ of the angled members 102 e and 102 f of the arms 102 a. When the end 102 a′ of the angled member 102 e is attached to the substantially cylindrical second base member 104, the angled member 102 e undergoes a “quarter twist” along its length in a clockwise direction, between the end 102 a′ attached to the substantially cylindrical second base member 104 and the other end 102 a″ where the male attachment member 102 d is located. Similarly, when the angled member 102 f of the arm 102 a is attached to the substantially cylindrical second base member 104, the angled member 102 f undergoes a “quarter twist” along its length in an anticlockwise direction, between the one end 102 a′ attached to the substantially cylindrical second base member 104 and the other end 102 a″ where the male attachment member 102 d is located. In an embodiment, the angled members 102 e and 102 f are inclined at an angle ranging, for example, between 15 degrees to 75 degrees relative to the ground surface. In one or more embodiments, the angled members 102 e and 102 f are retractable or extendable using mechanisms such as a telescopic means and the like. In other embodiments, the angled members 102 e and 102 f are selectively extendable or retractable based on an operator preference.

FIG. 1E exemplarily illustrates a front view of the wheel support assembly 103 of the all-terrain load transport system 100 shown in FIGS. 1A-1B and FIGS. 2-3 . FIG. 1E shows the wheel support assembly 103 extending from the ends 102 a′ of the arms 102 a. FIG. 1F exemplarily illustrates a rear view of the wheel support assembly 103 of the all-terrain load transport system 100. FIG. 1G exemplarily illustrates a rear perspective view of the wheel support assembly 103 of the all-terrain load transport system 100.

FIG. 1H exemplarily illustrates a top plan view of the all-terrain load transport system 100. The structure of the all-terrain load transport system 100 comprising the handle 109, the substantially cylindrical first base member 101, the three pairs of arms 102 a, 102 b, and 102 c, and the corresponding wheel support assemblies 103 is disclosed in the detailed descriptions of FIGS. 1A-1G. Each of the pairs of arms 102 a, 102 b, and 102 c comprises a pair of angled members 102 e and 102 f that project laterally from the sides of the substantially cylindrical second base member 104. As exemplarily illustrated in FIG. 1H, the wheel support assemblies 103 of the pairs of arms 102 a, 102 b, and 102 c are positioned at vertices 200 a, 200 b, and 200 c of an imaginary polygon 200 respectively. In an embodiment, the imaginary polygon 200 is an equilateral triangle. The pneumatic, omnidirectional wheel support assemblies 103 are evenly spaced in a triangular configuration. In alternative embodiments, the imaginary polygon 200 is a square, a pentagon, a hexagon, and similar variants. The number of wheel support assemblies 103 increase or decrease based on the structure of the imaginary polygon 200. As such, in the embodiments where the polygon is a square, the all-terrain load transport system 100 contains at least four wheel support assemblies 103. Alternatively, in embodiments where the imaginary polygon 200 is a pentagon, the all-terrain load transport system 100 contains at least five wheel support assemblies 103.

FIG. 2 exemplarily illustrates a top perspective view of the all-terrain load transport system 100. As disclosed in the detailed description of FIG. 1A, the all-terrain load transport system 100 comprises the substantially cylindrical first base member 101, at least three pairs of arms 102 a, 102 b, and 102 c, and the corresponding wheel support assemblies 103. The wheel support assemblies 103 are positioned at the vertices 200 a, 200 b, and 200 c of an imaginary polygon 200 as disclosed in the detailed description of FIG. 1H. The imaginary polygon 200 is coaxial to a longitudinal axis 202 of the substantially cylindrical first base member 101. In an embodiment, non-roller parts, for example, the substantially cylindrical first base member 101, the three pairs of arms 102 a, 102 b, and 102 c, the handle 109, etc., of the all-terrain load transport system 100, are made of conventional materials using conventional techniques. For example, the non-roller parts are made of cast steel, forged steel, or welded steel construction. If lightweight parts of less durability are required, these parts are constructed from plastic, for example, a fiber-reinforced plastic. Examples of suitable fibers for manufacturing the non-roller parts are boron, carbon, and glass. Examples of suitable plastics for manufacturing the non-roller parts are polyesters, polyurethanes, epoxides, and polyethers. In an embodiment, the spherical wheel 105 of each wheel support assembly 103 is constructed, for example, of steel, a resilient material, or an elastomer. In an embodiment, the elastomer is reinforced with a filler such as carbon black or is unreinforced. The elastomer used is, for example, natural rubber or a synthetic elastomer such as styrene-butadiene rubber, polyurethane rubber, neoprene rubber, or nitrile rubber. In another embodiment, the spherical wheel 105 is made of a non-marring material, for example, silicone or a combination of silicone and rubber for fragile flooring. The spherical wheel 105 is configured to move omnidirectionally within each wheel support assembly 103 with the assistance of roller bearings 106 to reduce friction.

FIG. 3 exemplarily illustrates a front elevation view of the all-terrain load transport system 100. As disclosed in the detailed description of FIG. 1A, the all-terrain load transport system 100 comprises the substantially cylindrical first base member 101, at least three pairs of arms 102 a, 102 b, and 102 c, and the wheel support assembly 103 in each pair. Several attachment members 110 are disposed at various locations along the substantially cylindrical first base member 101 for removably attaching one or more accessory equipment to the all-terrain load transport system 100. In an embodiment, the handle 109 is secured to one of the attachment members 110 for maneuvering the all-terrain load transport system 100.

FIG. 4A exemplarily illustrates a top plan view of the all-terrain load transport system 100. FIG. 4B exemplarily illustrates a cross-sectional view of the wheel support assembly 103 of the all-terrain load transport system 100, where the cross-section is obtained along a line 4B-4B′ shown in FIG. 4A. The wheel support assemblies 103 are positioned at the vertices 200 a, 200 b, and 200 c of the imaginary polygon 200 as disclosed in the detailed descriptions of FIG. 1H and FIG. 2 . In the embodiment where the imaginary polygon 200 is an equilateral triangle, the pneumatic, omnidirectional wheel support assemblies 103 are evenly spaced in a triangular configuration. In an embodiment, pneumatic, omnidirectional spherical wheels 105 are disposed in the arms 102 a, 102 b, and 102 c of the all-terrain load transport system 100 within their respective wheel support assemblies 103. The arms 102 a, 102 b, and 102 c are attached outside the perimeter 201 of the substantially cylindrical first base member 101 as exemplarily illustrated in FIG. 2 . Furthermore, the arms 102 a, 102 b, and 102 c are attached to the bottom end 111 of the substantially cylindrical first base member 101 exemplarily illustrated in FIG. 1B, from where the arms 102 a, 102 b, and 102 c extend outward and away from the longitudinal axis 202 of the substantially cylindrical first base member 101 illustrated in FIG. 2 . Positioning the wheel support assemblies 103 outside the perimeter 201 of the substantially cylindrical first base member 101, attached to the ends 102 a′ of the arms 102 a, 102 b, and 102 c increases the stability of the all-terrain load transport system 100 when the all-terrain load transport system 100 is in motion. Moreover, positioning the wheel support assemblies 103 outside the perimeter 201 of the substantially cylindrical first base member 101, on the arms 102 a, 102 b, and 102 c, ensures that the center of gravity of the all-terrain load transport system 100 is proximal to or suspended in the center of the all-terrain load transport system 100, thereby positioning a gravitational load below a center point of each wheel support assembly 103. Furthermore, positioning the wheel support assemblies 103 outside the perimeter 201 of the substantially cylindrical first base member 101, on the arms 102 a, 102 b, and 102 c, provides greater stability and decreases the incidences of tipping.

Roller bearings 106 positioned along an inner periphery 104 b of the substantially cylindrical second base member 104 exemplarily illustrated in FIG. 1A, facilitate the omnidirectional movement of the spherical wheels 105 within their respective wheel support assemblies 103. Each roller bearing 106 is securely seated within a housing 106 c as exemplarily illustrated in FIGS. 4C-4D. The housings 106 c that accommodate the roller bearings 106 are disposed along an interior surface 401 a of a sidewall 401 of the wheel support assembly 103 as exemplarily illustrated in FIG. 4B.

FIG. 4C exemplarily illustrates a side view of a roller bearing 106 configured to secure and move the spherical wheel 105 of the wheel support assembly 103 of the all-terrain load transport system 100. FIG. 4D exemplarily illustrates a partial sectional view of the roller bearing 106 shown in FIG. 4C. In an embodiment, the roller bearing 106 is a Roller CY-8H ball bearing. The roller bearing 106 comprises a rolling element 106 a seated within a housing 106 c. The housing 106 c comprises a flanged opening 106 b such that a portion of the housed rolling element 106 a is exposed to contact the spherical wheel 105 as exemplarily illustrated in FIG. 4B.

In an embodiment, the pneumatic spherical wheels 105 made, for example, of rubber, are configured to offer maximum displacement over varied terrain conditions, for example, over an even terrain or an uneven terrain. As used herein, the term “displacement” refers to the amount of contact that a part of the spherical wheel 105 makes with the terrain. The spherical wheels 105 are also configured to provide maximum displacement over a wide range of terrains, for example, sand, dirt, mud, gravel, snow, grass, various paved or man-made surfaces, etc. The spherical wheels 105 do not dig, sink, or cut into the material of the terrain on which the spherical wheels 105 are traversing, making the spherical wheels 105 suitable for use in a wide range of terrains. The arms 102 a, 102 b, and 102 c of the all-terrain load transport system 100 are removable. The arms 102 a, 102 b, and 102 c are replaceable with arms of an alternative configuration to increase the height or clearance of the all-terrain load transport system 100. In an embodiment, the arms 102 a, 102 b, and 102 c of an alternative configuration comprise spherical wheels 105 made of alternative wheel materials, for example, a non-marring material for fragile flooring. In another embodiment, the arms 102 a, 102 b, and 102 c of an alternative configuration are of a compact dimension for storage or transport.

FIG. 5 exemplarily illustrates a left-side view of the all-terrain load transport system 100. The handle 109 of the all-terrain load transport system 100 is removably attached to an attachment member 110 disposed on the outer periphery 101 a of the substantially cylindrical first base member 101. In an embodiment, supplementary attachment members 110 are disposed at multiple locations along the substantially cylindrical first base member 101. In an embodiment, the attachment members 110 are configured to receive or engage with one of a latching attachment, a hitching attachment, a securing means, etc., to securely retain one or more pieces of accessory equipment or load mounted on the all-terrain load transport system 100. The attachment members 110 of the all-terrain load transport system 100 are useful while transporting loads on an uneven terrain. The substantially cylindrical first base member 101, the arms 102 a, 102 b, and 102 c, and the wheel support assemblies 103 form the foundation of the all-terrain load transport system 100, thereby allowing usage of the all-terrain load transport system 100 as a multi-utility equipment system and a transport vehicle, and allowing the portability of a multitude of applications. The intended initial applications for the all-terrain load transport system 100 comprise, for example, a paint sprayer, a composter, a dumpcart, a pressure sprayer, a beverage and food cooler, an air compressor, a vacuum cleaning equipment, etc. The all-terrain load transport system 100 functions as a load bearing omnidirectional platform or accessory equipment platform based on user requirement as exemplarily illustrated in FIGS. 6-13 .

In an embodiment, an inner diameter of the substantially cylindrical first base member 101 of the all-terrain load transport system 100 is, for example, about 10 inches. In another embodiment, the all-terrain load transport system 100 comprises multiple substantially cylindrical first base members 101, each having a different inner diameter. For example, if the all-terrain load transport system 100 comprises five substantially cylindrical first base members 101, the inner diameter of the smallest substantially cylindrical first base member 101 is less than about 10 inches, and the inner diameter of the largest substantially cylindrical first base member 101 is more than about 15 inches. In an embodiment, the substantially cylindrical first base member 101 is radially adjustable to securely mount equipment having different peripheral diameters. In another embodiment, the interior space 114 defined by the substantially cylindrical first base member 101 exemplarily illustrated in FIG. 1A and FIG. 2 , is tapered inward slightly from top to bottom, making an accessory equipment disposed within the space 114 defined by the substantially cylindrical first base member 101 similar to seating a cork or a stopper in a bottle. The weight of the accessory equipment or downforce keeps the accessory equipment seated within the space 114, translating to a lowered center of gravity thereby improving the overall stability of the all-terrain load transport system 100. In an embodiment, a lip 113 is provided on a substantially mid-portion or a substantially lower portion of the cylindrical first base member 101 as exemplarily illustrated in FIG. 1A, FIG. 1C, FIG. 1H, FIG. 2 , and FIG. 4A, to limit downward travel or movement of the mounted accessory equipment. In an embodiment, the lip 113 is keyed or grooved to align the accessory equipment to the all-terrain load transport system 100. In another embodiment, instead of the lip 113, a platform is provided on the cylindrical first base member 101 to limit downward travel or movement of the mounted accessory equipment.

FIG. 6 exemplarily illustrates a top perspective view of a welding accessory 600 mounted on the all-terrain load transport system 100. In an embodiment, the all-terrain load transport system 100 is fitted with a circular support platform 601 configured to receive and mount a piece of accessory equipment, for example, the welding accessory 600, on the all-terrain load transport system 100.

In an embodiment, the trash can accessory 1300 is solar powered and configured to store harvested energy in a battery or similar power source. The roller bearings 106 positioned along the inner periphery 104 b of the substantially cylindrical second base member 104 of each wheel support assembly 103 in the all-terrain load transport system 100 exemplarily illustrated in FIGS. 1A-1B and FIG. 2 , facilitates omnidirectional movement of the spherical wheel 105 in each wheel support assembly 103, thereby allowing transportation of each individual accessory 700, 800, 900, 1000, 1100, 1200, or 1300 mounted on the all-terrain load transport system 100.

The maneuverability of the all-terrain load transport system 100 allows a 360-degree turning radius for navigating through tight spots or narrow spaces. Furthermore, the low center of gravity makes the all-terrain load transport system 100 less prone to tipping and therefore compact and robust while towing a mounted accessory or tool to a location. Moreover, the resilient omnidirectional spherical wheels 105 of the all-terrain load transport system 100 are capable of handling diverse terrains that may be encountered at a work location or a remote site. In an embodiment, the all-terrain load transport system 100 is configured to be transported in a standard kit comprising reusable or recyclable components and accessories. As such, the provision of the all-terrain load transport system 100 at work locations saves valuable time required for procedures such as installation, repair, routine maintenance, etc. In an embodiment, the kit comprises several accessories such as vertical telescopic frames, cylindrical support frames, clamping members, fasteners, etc., provided with the all-terrain load transport system 100 to allow mounting of accessories or equipment of different geometric configurations on the all-terrain load transport system 100. In an embodiment, the accessories or components provided in the kit are made by an additive manufacturing process, for example, three-dimensional (3D) printing. In another embodiment, the accessories or components are manufactured using a conventional plastic molding process, for example, injection molding. In an embodiment, the components are manufactured from metals such as aluminum and the like for increased strength and durability. In this embodiment, the components of the all-terrain load transport system 100 are spray-coated or coated with anti-corrosive coatings.

In an embodiment, the all-terrain load transport system 100 further comprises onboard electronics for providing an improved user experience. In this embodiment, the all-terrain load transport system 100 comprises one or more processors, microcontrollers, and/or printed circuit boards (PCBs) in addition to sensors configured to detect one or more parameters in relation to the all-terrain load transport system 100.

In another embodiment, the all-terrain load transport system 100 comprises large and powerful battery packs capable of delivering varying voltage outputs of both alternating current (AC) and direct current (DC) power. In an embodiment, these voltage outputs are configured to provide relatively high levels of DC power for powering equipment that is attached to various powered attachment points on the all-terrain load transport system 100, while also being configured to provide AC power to function as a generator for tools mounted on the all-terrain load transport system 100. As such, the all-terrain load transport system 100, in accordance with the disclosure herein, is configured to deliver a relatively large amount of power, for example, sufficient to supply power to powered equipment and accessories coupled to the powered attachment points on the all-terrain load transport system 100. This supply of power and capability at a work site allows workers at a work site to accomplish tasks on site without the use of gas-powered equipment, extension cords, lifting/hoisting equipment, excessive manual labor, etc., thereby benefitting the work sites that have limited access to an external power supply which is not easily accessible.

In an exemplary implementation, the sensors comprise proximity sensors, motion sensors, load sensors, etc., configured to detect parameters such as the proximity of other objects to the all-terrain load transport system 100, the load mounted on the all-terrain load transport system 100, etc. In an embodiment, the detected parameters are indicated to a user using haptic feedback, an audio notification, or a visual indication via a graphic user interface or a display unit. In an embodiment, the detected parameters are further transmitted to a central database, or a receiving unit configured within a similar all-terrain load transport system 100, or a computing unit such as a personal computer, a laptop, and/or a smartphone, for processing, analytics, and executing control actions. Based on the detected parameters at a work site terrain, the all-terrain load transport system 100 is conveniently maneuvered through standard sized doorways, aisles, hallways, tight turns, etc. In some implementations, the all-terrain load transport system 100 operates in multiple modes comprising, for example, a follow mode and other modes that allow additional flexibility and adaptability in the use of the all-terrain load transport system 100. In various embodiments, the all-terrain load transport system 100 is remotely controlled and/or monitored and the data received therefrom is analyzed and processed to optimize the operation of the all-terrain load transport system 100.
